Recent neurophysiological studies have shown that the parietal cortex can be classified into sub-regions and that those regions play different roles in information processing for spatial vision. Stereopsis is the ability to perceive depth of the visual world based on images projected on the two retinae. Binocular disparities are crucial cues for building a 3D representation of the visual world, however, monocular depth cues, such as texture, shading, and linear perspective are also very important for that. Marr (Marr 1982) postulated in his theory of vision that an important step in visual information processing for 3D representation of an object is the description of the geometry of the visible surface, especially that of the surface orientation and curvature. Several kinds of disparity cues and monocular cues for the representation of surface orientation have been demonstrated from psychophysical studies. Integrative processing of these different types of depth cues is necessary to build a neural representation of the surface orientation. We examined the properties of surface orientation selective (SOS) neurons in the caudal part of the lateral bank of the intraparietal sulcus (area CIP) of alert monkeys, and identified a group of neurons which are sensitive to binocular disparity cues and also monocular depth cues. We also found that the neurons in the area CIP responded to curved surface defined by the Koenderink's formula. These neurons may contribute to the representation of the 3D feature of objects in the visual world.

最近的神经生理学研究表明，顶叶皮层可以分为不同的子区域，这些区域在空间视觉的信息处理中发挥着不同的作用。立体视觉是基于投射在两个视网膜上的图像感知视觉世界的深度的能力。双目视差是构建视觉世界的3D表示的关键线索，然而，单目深度线索，如纹理，阴影和线性透视也非常重要。马尔（马尔1982）在他的视觉理论中假设，用于物体的3D表示的视觉信息处理的重要步骤是对可见表面的几何形状的描述，特别是对表面取向和曲率的描述。心理物理学研究已经证明了几种视差线索和单眼线索的表面方向的表征。这些不同类型的深度线索的综合处理是必要的，以建立一个表面方向的神经表示。我们研究了警觉猴顶内沟外侧沟（CIP区）尾侧部表面方向选择（SOS）神经元的特性，并确定了一组对双眼视差线索和单眼深度线索敏感的神经元。我们还发现CIP区的神经元对Koenderink公式定义的曲面有反应。这些神经元可能有助于在视觉世界中的物体的三维特征的表示。
